Integrin ligands

ABSTRACT

The invention relates to novel compounds which bind to integrin receptors, their use as ligands of integrin receptors, in particular as ligands of the α v β 3  integrin receptor, their use, and pharmaceutical preparations comprising these compounds.

[0001] The present invention relates to novel compounds which bind to integrin receptors, their use as ligands of integrin receptors, in particular as ligands of the α_(v)β₃ integrin receptor, their use, and pharmaceutical preparations comprising these compounds.

[0002] Integrins are cell surface glycoprotein receptors which mediate interactions between identical and different cells as well as between cells and extracellular matrix proteins. They are involved in physiological processes, such as embryogenesis, hemostasis, wound healing, immune response and formation/maintenance of the tissue architecture.

[0003] Disturbances in the gene expression of cell adhesion molecules and functional disorders of the receptors can contribute to the pathogenesis of many disorders, such as tumors, thromboembolic events, cardiovascular disorders, lung diseases, disorders of the CNS, the kidney, the gastrointestinal tract or inflammations.

[0004] Integrins are heterodimers of an α- and a β-transmembrane subunit in each case, which are noncovalently bonded. Up to now, 16 different α- and 8 different β-subunits and 22 different combinations have been identified.

[0005] Integrin α_(v)β₃, also called the vitronectin receptor, mediates adhesion to a multiplicity of ligands-plasma proteins, extracellular matrix proteins, cell surface proteins, of which the majority contain the amino acid sequence RGD (Cell, 1986, 44, 517-518; Science 1987, 238, 491-497), such as vitronectin, fibrinogen, fibronectin, von Willebrand factor, thrombospondin, osteopontin, laminin, collagen, thrombin, tenascin, MMP-2, bone sialoprotein II, various viral, fungal, parasitic and bacterial proteins, natural integrin antagonists such as disintegrins, neurotoxins—mambin—and blood fluke proteins—decorsin, ornatin—and also some non-RGD ligands, such as Cyr-61 and PECAM-1 (L. Piali, J. Cell Biol. 1995, 130, 451-460; Buckley, J. Cell Science 1996, 109, 437-445, J. Biol. Chem. 1998, 273, 3090-3096).

[0006] A number of integrin receptors show cross-reactivity with ligands' which contain the RGD motif. Thus integrin α_(IIb)β₃, also called the platelet fibrinogen receptor, recognizes fibronectin, vitronectin, thrombospondin, von Willebrand factor and fibrinogen.

[0007] Integrin α_(v)β₃ is expressed, inter alia, from endothelial cells, blood platelets, monocytes/macrophages, smooth muscle cells, some B cells, fibroblasts, osteoclasts and various tumor cells, such as melanoma, glioblastoma, lung, breast, prostate and bladder carcinomas, osteosarcomas or neuroblastomas.

[0008] Increased expression is observed under various pathological conditions, such as in the prothrombotic state, in vascular injury, tumor growth or metastasis or reperfusion and on activated cells, in particular on endothelial cells, smooth muscle cells or macrophages.

[0009] An involvement of integrin α_(v)β₃ has been demonstrated, inter alia, in the following syndromes:

[0010] cardiovascular disorders such as atherosclerosis, restenosis after vascular injury, and angioplasty (neointima formation, smooth muscle cell migration and proliferation) (J. Vasc. Surg. 1994, 19, 125-134; Circulation 1994, 90, 2203-2206),

[0011] acute kidney failure (Kidney Int. 1994, 46, 1050-1058; Proc. Natl. Acad. Sci. 1993, 90, 5700-5704; Kidney Int. 1995, 48, 1375-1385),

[0012] angiogenesis-associated microangiopathies such as diabetic retinopathy or rheumatoid arthritis (Ann. Rev. Physiol 1987, 49, 453-464; Int. Ophthalmol. 1987, 11, 41-50; Cell 1994, 79, 1157-1164; J. Biol. Chem. 1992, 267, 10931-10934),

[0013] arterial thrombosis,

[0014] stroke (phase II studies with ReoPro, Centocor Inc., 8th annual European Stroke Meeting),

[0015] carcinomatous disorders, such as in tumor metastasis or in tumor growth (tumor-induced angiogenesis) (Cell 1991, 64, 327-336; Nature 1989, 339, 58-61; Science 1995, 270, 1500-1502),

[0016] osteoporosis (bone resorption after proliferation, chemotaxis and adhesion of osteoclasts to bone matrix) (FASEB J. 1993, 7, 1475-1482; Exp. Cell Res. 1991, 195, 368-375, Cell 1991, 64, 327-336),

[0017] high blood pressure (Am. J. Physiol. 1998, 275, H1449-H1454),

[0018] psoriasis (Am. J. Pathol. 1995, 147, 1661-1667),

[0019] hyperparathyroidism,

[0020] Paget's disease (J. Clin. Endocrinol. Metab. 1996, 81, 1810-1820),

[0021] malignant hypercalcemia (Cancer Res. 1998, 58, 1930-1935),

[0022] metastatic osteolytic lesions (Am. J. Pathol. 1997, 150, 1383-1393),

[0023] pathogen protein (e.g. HIV-1 tat)-induced processes (e.g. angiogenesis, Kaposi's sarcoma) (Blood 1999, 94, 663-672)

[0024] inflammation (J. Allergy Clin. Immunol. 1998, 102, 376-381),

[0025] cardiac insufficiency, CHF, and also in

[0026] antiviral, antiparasitic, antifungal or antibacterial therapy and prophylaxis (adhesion and internalization) (J. Infect. Dis. 1999, 180, 156-166; J. Virology 1995, 69, 2664-2666; Cell 1993, 73, 309-319).

[0027] On account of its key role, pharmaceutical preparations which contain low-molecular weight integrin α_(v)β₃ ligands are of high therapeutic or diagnostic benefit, inter alia, in the indications mentioned.

[0028] Advantageous α_(v)β₃ integrin receptor ligands bind to the integrin α_(v)β₃ receptor with an increased affinity.

[0029] In contrast to integrin α_(v)β₃, particularly advantageous α_(v)β₃ integrin receptor ligands additionally have an increased selectivity and are less active with respect to the integrin α_(IIb)β₃ by at least a factor of 10, preferably at least a factor of 100.

[0030] For a multiplicity of compounds, such as anti-α_(v)β₃ monoclonal antibodies, peptides which contain the RGD binding sequence, natural, RGD-containing proteins (e.g. disintegrins) and low-molecular weight compounds, an integrin α_(v)β₃ antagonistic action has been shown and a positive in vivo effect demonstrated (FEBS Letts 1991, 291, 50-54; J. Biol. Chem. 1990, 265, 12267-12271; J. Biol. Chem. 1994, 269, 20233-20238; J. Cell Biol 1993, 51, 206-218; J. Biol. Chem. 1987, 262, 17703-17711; Bioorg. Med. Chem. 1998, 6, 1185-1208).

[0032] EP 540 334 describes bicyclic antagonists of the α_(IIb)β₃ integrin receptor.

[0033] U.S. Pat. No. 5,565,449 describes bicyclic gp_(IIb)β₃ receptor antagonists.

[0035] Further, photographic processing aids having a cyclic molecular structure are described in EP 908764.

[0343] A branched or unbranched, optionally substituted C₁-C₆-alkyl, C₁-C₆-alkoxyalkyl, C₂-C₆-alkenyl, C₂-C₁₂-alkynyl or arylalkyl radical or an optionally substituted aryl, hetaryl or C₃-C₇-cycloalkyl for R_(E) ¹¹ and RE¹¹* in structural element E independently of one another is understood as meaning, for example, the corresponding radicals described above for R_(G) ⁷.

[0344] The branched or unbranched, optionally substituted radicals CO—C₁-C₆-alkyl, CO—O—C₁-C₆-alkyl, CO—NH—C₁-C₆-alkoxalkyl, CO—NH—C₁-C₆-alkyl or SO₂—C₁-C₆-alkyl radical or the optionally substituted radicals Co-O-alkylenearyl, CO—NH-alkylenearyl, CO-alkylenearyl, CO-aryl, CO—NH-aryl, SO₂-aryl, CO-hetaryl, SO₂-alkylenearyl, SO₂-hetaryl or SO₂-alkylenehetaryl for R_(E) ¹¹ and R_(E) ¹¹* independently of one another are composed, for example, of the corresponding groups CO, COO, CONH or SO₂ and the corresponding radicals mentioned above.

[0345] Preferred radicals for R_(E) ¹¹ or R_(E) ¹¹* are independently of one another hydrogen, a branched or unbranched, optionally substituted C₁-C₆-alkyl, C₁-C₆-alkoxy, C₂-C₆-alkenyl,

[0346] C₂-C₁₂-alkynyl or arylalkyl radical, or an optionally substituted hetaryl or C₃-C₇-cycloalkyl radical.

[0347] Particularly preferred radicals for R_(E) ¹¹ or R_(E) ¹¹* are hydrogen, methyl, cyclopropyl, allyl or propargyl.

[0348] In a particularly preferred embodiment of structural element E₁, structural element E₁ is a radical —CH₂—CH₂—CO—, —CH₂—CH₂—CH₂—CO— or a C₁-C₅-alkylene radical.

[0349] In a particularly preferred embodiment of structural element E, the spacer structural element E used is a structural element of the formula I_(E1E2)

-E₂-E₁-  I_(E1E2)

[0350] where the structural elements E₂ and E₁ have the meanings described above.

[0351] Preferred structural elements E are composed of at least one preferred radical of the radicals belonging to structural element E, while the remaining radicals are widely variable.

[0352] Particularly preferred structural elements E are composed of the preferred radicals of structural element E.

[0353] Preferred structural elements B are composed either of the preferred structural element A, while E is widely variable or of the preferred structural element E, while A is widely variable.

[0354] The compounds of the formula I, and also the intermediates for their preparation, can have one or more asymmetric substituted carbon atoms. The compounds can be present as pure enantiomers or pure diastereomers or as a mixture thereof. The use of an enantiomerically pure compound as the active compound is preferred.

[0355] The compounds of the formula I can also be present in other tautomeric forms.

[0356] The compounds of the formula I can also be present in the form of physiologically tolerable salts.

[0357] The compounds of the formula I can also be present as prodrugs in a form in which the compounds of the formula I are liberated under physiological conditions. By way of example, reference may be made here to the group T in structural element L, which in some cases contains groups which are hydrolyzable to the free carboxylic acid group under physiological conditions. Derivatized structural elements B or A are also suitable which liberate the structural element B or A respectively under physiological conditions.

[0358] In preferred compounds of the formula I, in each case one of the three structural elements B, G or L has the preferred range, while the remaining structural elements are widely variable.

[0359] In particularly preferred compounds of the formula I, in each case two of the three structural elements B, G or L have the preferred range, while the remaining structural elements are widely variable.

[0360] In very particularly preferred compounds of the formula I, in each case all three structural elements B, G or L have the preferred range, while the remaining structural element is widely variable.

[0361] Preferred compounds of the formula I contain, for example, the preferred structural element G, while the structural elements B and L are widely variable.

[0362] In particularly preferred compounds of the formula I, for example, B is replaced by the structural element A-E- and the compounds contain, for example, the preferred structural element G and the preferred structural element A, while the structural elements E and L are widely variable.

[0363] Further particularly preferred compounds of the formula I contain, for example, the preferred structural element G and the preferred structural element A, while the structural elements E and L are widely variable.

[0364] Very particularly preferred compounds of the formula I in which A-E- is B- are listed below, the number before the text block being the number of an individualized compound of the formula I, and in the text block A-E-G-L the abbreviations being separated by a bonding dash in each case for an individual structural element A, E, G or L and the meaning of the abbreviations of the structural elements being explained after the table.

[0926] The compounds of the formula I and the starting substances used for their preparation can generally be prepared by methods of organic chemistry known to the person skilled in the art, such as are described in standard works such as Houben-Weyl (ed.), “Methoden der Organischen Chemie”[Methods of Organic Chemistry], Thieme-Verlag, Stuttgart, Taylor (ed.), “The Chemistry of Heterocyclic Compounds”, Wiley & Sons, New York, or March “Advanced Organic Chemistry”, 4^(th) Edition, Wiley & Sons. Further methods of preparing specific functional groups are also described in R. Larock, “Comprehensive Organic Transformations”, Weinheim 1989, in particular the preparation of alkenes, alkynes, halides, amines, ethers, alcohols, phenols, aldehydes, ketones, nitrites, carboxylic acids, esters, amides and acid chlorides.

[0927] Generally, syntheses of the compounds of the formula I are possible in very different ways (Scheme 1). The linkage of the individual units A′, E′, G′ or L′, which are appropriately activated or modified compared with the structural elements A, E, G or L, can be carried out in any desired sequence (equations 1a+b). The linkage of subunits according to equation 2 is also possible, so that the synthesis of the molecules can also take place between parts of a structural element, for example between E_(I) and E_(II). The symbol “'” in a unit or subunit stands for an activated unit or subunit or for a structural element which is synthesized, or contains a unit of the substructural elements which are removed again in the synthesis of the compounds of the formula I, such as leaving groups.

[0928] In these reactions, it is to be taken into account that protective groups possibly present in the subunits can be necessary, which have previously had to be introduced into the molecule and removed after the critical steps. A general survey of the protective groups, their introduction, stability and removal is given in Th. Greenes “Protective Groups in Organic Synthesis”, Wiley & Sons, New York 1991. As a rule, the activation of the units in the sense of the desired reaction is possible by a number of reagents.

[0929] If not stated otherwise, all starting materials and reagents are commercially available, or can be prepared from commercially obtainable precursors according to customary or specific methods known from the literature (Beilstein).

[0930] Solvents which can be used are all customary inert solvents, such as hydrocarbons such as hexane, heptane, petroleum ether, toluene, benzene or xylene; chlorinated hydrocarbons such as trichloroethylene, 1,2-dichloroethane, carbon tetrachloride, chloroform, dichloromethane; alcohols such as methanol, ethanol, isopropanol, n-propanol, n-butanol or tert-butanol; ethers such as diethyl ether, methyl tert-butyl ether, diisopropyl ether, tetrahydrofuran, dioxane; glycol ethers such as ethylene glycol monomethyl ether or monoethyl ether, ethylene glycol dimethyl ether; ketones such as acetone, butanone; amides such as dimethylformamide (DMF), dimethylacetamide or acetamide; sulfoxides such as dimethyl sulfoxide, sulfolane; pyridine, N-methylpyrrolidone, 1,3-dimethyltetrahydro-2(1H)-pyrimidinone (DMPU), 1,3-dimethyl-2-imidazolidinone; nitriles such as acetonitrile or propionitrile; water, mixtures of the solvent mentioned or related mixtures such as organofluorine phases in combination with abovementioned solvents.

[0931] The synthesis of compounds of the formula I can either be carried out by the “classical” method in solution or on a polymer support, in each case reaction conditions being used such as are known and are suitable for the respective reactions. Use can also be made in this case of variants which are known per se, but not mentioned here.

[0932] Syntheses of the units G′ can be found, for example, in “The Chemistry of Heterocyclic Compounds”, Volume 50, “Bicyclic Diazepines” or Volume 43, “Azepines”, Wiley & Sons, New York 1991. In order to demonstrate the breadth of possible application, exemplary literature syntheses of various substituted, aromatic and heteroaromatic azepinones and diazepinones are listed below:

[0934] In Scheme 2, the use of such fragments in the case of the benzodiazepinones is shown. These can be doubly alkylated, for example, using esters of bromoacetic acid (J. Org. Chem. 1949, 14, 1099,; J. Am. Chem. Soc. 1952, 74, 1010), orthogonally cleavable diesters being accessible as in ST-7. These can be cleaved bilaterally and reacted with fragments A-E_(I)′, as is shown here for one example. After the removal of possible protective groups, compounds according to the general formula I (here: ST-9) are obtained. It is demonstrated with ST-7 how the incorporation of the element G can take place in both orientations, in that alternatively both carboxylic acids are employed for the lengthening. In Scheme 2, it is also demonstrated how after introduction of a protective group SG₁ the selective alkylation of the amide nitrogen takes place to give compounds of the type ST-7a, which after removal of the protective group SG₁ opens up the possibility of synthesizing the compounds of the formula I using suitable fragments R⁴—X_(1g) (inter alia halides, alkoxysulfonic acid esters, carboxylic acids in activated form, sulfonic acid chlorides, isocyanates, chloroformic acid esters, where X_(1g)=leaving group) (ST-8).

[0935] The linkage of the units G to the adjacent fragments can also be carried out, for example, by Wittig/Horner reactions (starting from ketones). Structures of the type W_(G)=I_(WG) ² to I_(WG) ⁴ are accessible thereby (Scheme 3, ST-10a-c). Synthesis of ethers is made possible by reduction of the ketone, for example with NaBH₄ (H. O. House, “Modern synthetic Reactions”, Benjamin, N.Y. 1972, p. 42) and alkylation of the alcohol with suitable electrophiles (ST-11). Carrying out the reductive amination of the ketone, for example with NaBH₃(CN) or NaBH(OAc)₃ (J. Am. Chem. Soc. 1986, 108, 1039) leads to amines (ST-12).

[0936] The synthesis of the units or fragments L′ or E′ needed is carried out by the already mentioned general methods of organic chemistry. The synthesis of some of these units is described by way of example in the experimental section. In the case in which the fragments Q_(E) and X_(E) are a hetaryl radical, the units used are either commercially available or accessible by methods known to the person skilled in the art. A large number of preparation methods are described in detail in Houben-Weyl's “Methoden der organischen Chemie” [Methods of organic chemistry] (Vol. E6: Furans, thiophenes, pyrroles, indoles, benzothiophenes, furans, -pyrroles; Vol. E7: Quinolines, pyridines, Vol. E8: Isoxazoles, oxazoles, thiazoles, pyrazoles, imidazoles and their benzo-fused representatives, and also oxadiazole, thiadiazoles and triazoles; Vol. E9: Pyridazines, pyrimidines, triazines, azepines and their benzo-fused representatives and also purines).

[0937] The synthesis of the units and fragments A′ or the linkage thereof with the elements R-E′ (where R is alternatively a part or the entire radical of the molecule corresponding to the general formula I) in some cases necessitates carrying out methods which are not generally known but which are described in the literature, which should therefore be mentioned here. Some methods are also mentioned, for example, in the patent application WO 9708145. At the same time, use can also be made of variants known per se, but not mentioned here.

[0938] For the synthesis and linkage of the fragments A′ to the fragments E′ or E_(I)′, fragments or subfragments E′ or E_(I)′, E′-G′ or E_(I)′-G′ or E′-G-L or E_(I)′-G-L of the general structure ST-13a-b can be used (Scheme 4). The nitrile in ST-13b is used here, for example, as a precursor for amines, imines, amidines, amides, carboxylic acids or N-containing heterocycles. Preferably, the nitrile is employed in the synthesis as an amine, amidine or heterocyclic precursor. Starting from the amines (ST-13a) and products of the nitrile reduction of ST-13b), it is possible to prepare, for example, aminoheteroaromatics, especially aminopyridines; aminopyrimidines; aminoazatetrahydroquinolines; aminoimidazoles, -benzimidazoles and also azabenzimidazoles; ureas; thioureas or guanidines.

[0939] R1=Fragment or subfragment E′, E′-G′, or E′-G-L Scheme 5 shows examples of the reaction of the amines ST-13a (Blakemoore et al. Eur. J. Med. Chem. 1987 (22) 2, 91-100, Misra et al. Bioorg. Med. Chem. Lett. 1994 4 (18), 2165-2170).

[0940] Various guanidine and amidine derivatives can be prepared by the methods shown in Scheme 6 by way of the example of the reactions of ST-13a (Synlett 1990, 745, J. Org. Chem. 1992, 57, 2497, Bioorg. Med. Chem. 1996, 6, 1185-1208; Bioorg. Med. Chem. 1998, 1185, oder Synth. Comm. 1998, 28, 741-746, Tetrahedron Lett. 1999, 40, 1103-1106, Applications US 3202660, Wo 9708145)

[0941] The following groups and subfragments A′ or A′-R1 can be prepared, for example, by methods known from the literatur: ST-15 (Phosphorus Sulfur Silicon Relat. Elem. 1991, 63, 283-293), ST-16 (Heterocycles 1998, 15 N′-1, Spec. Issue, 341-344; WO 9736859), ST-17 (Synthesis 1981, 963-965, Synth. Comm. 1997, 27 (15), 2701-2707), ST-18 (J. Org. Chem. 1991, 56 (6), 2260-2262) (Scheme 7).

[0942] The invention further relates to the use of the structural element of the formula I_(GL)

-G-L  I_(GL)

[0943] for the preparation of compounds which bind to integrin receptors.

[0944] The invention further relates to drugs comprising the structural element of the formula I_(GL).

[0945] The invention further relates to pharmaceutical preparations, comprising at least one compound of the formula I in addition to the customary pharmaceutical excipients.

[0946] The compounds according to the invention can be administered orally or parenterally (subcutaneously, intravenously, intramuscularly, intraperitoneally) in the customary manner. Administration can also be carried out through the nasopharynx using vapors or sprays. Further, the compounds according to the invention can be introduced by direct contact with the affected tissue.

[0947] The dose depends on the age, condition and weight of the patient and on the manner of administration. As a rule, the daily dose of active compound is between approximately 0.5 and 50 mg/kg of body weight in the case of oral administration and between approximately 0.1 and 10 mg/kg of body weight in the case of parenteral administration.

[0948] The novel compounds can be administered in solid or liquid form in the customary pharmaceutical administration forms, e.g. as tablets, film-coated tablet, capsules, powders, granules, coated tablets, suppositories, solutions, ointments, creams or sprays. These are prepared in a customary manner. The active compounds can in this case be processed using the customary pharmaceutical excipients such as tablet binders, fillers, preservatives, tablet disintegrants, flow regulators, plasticizers, wetting agents, dispersants, emulsifiers, solvents, release-delaying agents, antioxidants and/or propellants (cf. H. Sucker et al.: Pharmazeutische Technologie, Thieme-Verlag, Stuttgart, 1991). The administration forms thus obtained normally contain the active compound in an amount from 0.1 to 90% by weight.

[0949] The invention further relates to the use of compounds of the formula I for the production of drugs for treating illnesses. The compounds of the formula I can be used for treating human and animal illnesses. The compounds of the formula I bind integrin receptors. They are therefore preferably suitable as integrin receptor ligands and for the production of drugs for treating illnesses in which an integrin receptor is involved, in particular for the treatment of illnesses in which the interaction between integrins and their natural ligands is dysregulated, i.e. excessive or reduced.

[0950] Integrin receptor ligands are understood as meaning agonists and antagonists.

[0951] An excessive or decreased interaction is understood as meaning both an excessive or decreased expression of the natural ligand and/or of the integrin receptor and thus an excessive or decreased amount of natural ligand and/or integrin receptor or an increased or decreased affinity of the natural ligand for the integrin receptor.

[0952] The interaction between integrins and their natural ligands is dysregulated compared with the normal state, i.e. excessive or decreased, if this dysregulation does not correspond to the physiological state. An increased or decreased interaction can lead to pathophysiological situations.

[0953] The level of dysregulation which leads to a pathophysiological situation is dependent on the individual organism and on the site and nature of the disorder.

[0954] Preferred integrin receptors for which the compounds of the formula I according to the invention can be used are the α₅β₁, α₄β₁, gp_(IIb)β₃, α_(V)β₅ and α_(v)β₃ integrin receptors.

[0955] The compounds of the formula I particularly preferably bind to the α_(v)β₃ integrin receptor and can thus be particularly preferably used as ligands of the α_(v)β₃ integrin receptor and for the treatment of illnesses in which the interaction between α_(v)β₃ integrin receptor and its natural ligand is excessive or reduced.

[0956] The compounds of the formula I are preferably used for the treatment of the following illnesses:

[0957] cardiovascular disorders-such as atherosclerosis, restenosis after vascular injury or stent implantation, and angioplasty (neointima formation, smooth muscle cell migration and proliferation),

[0958] acute kidney failure,

[0959] angiogenesis-associated microangiopathies such as diabetic angiopathies or retinopathy or rheumatoid arthritis,

[0964] high blood pressure, psoriasis, hyperparathyroidism, Paget's disease, malignant hypercalcemia, metastatic osteolytic lesions, inflammation, wound healing, cardiac insufficiency, congestive heart failure CHF, as well as in

[0965] antiviral, antimycotic, antiparasitic or antibacterial therapy and prophylaxis (adhesion and internalization).

[0966] Advantageously, the compounds of the formula I can be administered in combination with at least one further compound in order to achieve an improved curative action in a number of indications. These further compounds can have the same or a different mechanism of action as/from the compounds of the formula I.

[0967] In addition to the compounds of the formula I and the customary pharmaceutical incipients, the pharmaceutical preparations can therefore contain at least one further compound, depending on the indication, in each case selected from one of the 10 groups below.

[1103] A solution of 8.8 g (35 mmol) of t-butyl diethylphosphonate in 12 ml of DME was added dropwise at 0° C. to a suspension of 1.4 g of NaH (50%, deoiled) in 12 ml of DMF and the mixture was stirred until the appearance of a clear yellow solution. Subsequently 25 ml of a DMF solution of 5.2 g (29.7 mmol) of 3,4-dihydro-1H-2-benzazepin-1,5(2H)-dione (Tetrahedron Lett. 1993, 34, 5855) were added dropwise at 0-5° C. and the mixture was stirred for 3.5 h, the reaction solution being allowed to rise to room temperature. For work-up, it was poured into 300 ml of cold 5% strength NaCl solution, the deposited product was extracted 4 times and with ethyl acetate, and the combined ethyl acetate phases were washed with 5% strength Na₂CO₃ and sodium chloride solution, dried over Na₂SO₄ and concentrated in vacuo to give a viscous yellow oil residue. The E/Z mixture was employed in the subsequent hydrogenation without further purification.
